The origins of Indian classical music can be found from the oldest of scriptures, part of the Hindu tradition, the Vedas. The Samaveda, one of the four Vedas, describes music at length. The Samaveda was created out of Rigveda so that its hymns could be sung as Samagana; this style evolved into jatis and eventually into ragas. Indian classical music has its origins as a meditation tool for attaining self realization. All different forms of these melodies (ragas) are believed to affect various “chakras” (energy centers, or “moods”) in the path of the Kundalini. However, there is little mention of these esoteric beliefs in Bharat’s Natyashastra, the first treatise laying down the fundamental principles of drama, dance and music.
